There are roughly two philosophical literatures on “happiness,” each corresponding to a different sense of the term. One uses ‘happiness’ as a value term, roughly synonymous with well-being or flourishing. The other body of work uses the word as a purely descriptive psychological term, akin to ‘depression’ or ‘tranquility’. An important project in the philosophy of happiness is simply getting clear on what various writers are talking about: what are the important meanings of the term and how do they connect? (...) While the “well-being” sense of happiness receives significant attention in the contemporary literature on well-being, the psychological notion is undergoing a revival as a major focus of philosophical inquiry, following on recent developments in the science of happiness. This entry focuses on the psychological sense of happiness (for the well-being notion, see the entry on well-being). The main accounts of happiness in this sense are hedonism, the life satisfaction theory, and the emotional state theory. Leaving verbal questions behind, we find that happiness in the psychological sense has always been an important concern of philosophers. Yet the significance of happiness for a good life has been hotly disputed in recent decades. Further questions of contemporary interest concern the relation between the philosophy and science of happiness, as well as the role of happiness in social and political decision-making. (shrink)

Francis Ysidro Edgeworth’s unduly neglected monograph New and Old Methods of Ethics (1877) advances a highly sophisticated and mathematized account of social well-being in the utilitarian tradition of his 19th-century contemporaries. This article illustrates how his usage of the ‘calculus of variations’ was combined with findings from empirical psychology and economic theory to construct a consequentialist axiological framework. A conclusion is drawn that Edgeworth is a methodological predecessor to several important methods, ideas, and issues that continue to be discussed in (...) contemporary social well-being studies.

Well-being measurements are frequently used to support conclusions about a range of philosophically important issues. This is a problem, because we know too little about the intervals of the relevant scales. I argue that it is plausible that well-being measurements are non-linear, and that common beliefs that they are linear are not truth-tracking, so we are not justified in believing that well-being scales are linear. I then argue that this undermines common appeals to both hypothetical and actual well-being measurements; I (...) first focus on the philosophical literature on prioritarianism and then discuss Kahneman’s Peak-End Rule as a systematic bias. Finally, I discuss general implications for research on well-being, and suggest a better way of representing scales. (shrink)

Much recent philosophical literature on happiness and satisfaction is based on the belief that empirical research is relevant to philosophical conclusions. In his2010 book What is This Thing Called Happiness? Fred Feldman begs to differ. He suggests that there is no evidence that empirical research is relevant to long-standing philosophical questions; consequently, that philosophers have little reason to pay attention to the work of psychologists or economists; and that philosophers need not fear embarrassing themselves by being ignorant of important scientific (...) findings that bear directly on their work. Relying on an example invoked by Feldman himself, this paper makes the case that all three theses are false. The argument suggests a picture according to which science and philosophy stand in a symbiotic relationship, with scientists and philosophers engaging in a mutually beneficial exchange of ideas for the advancement of thegeneral knowledge.

Since the 1970’s epidemiological measures focusing on “health-related quality of life” or simply “quality of life” have figured increasingly as endpoints in clinical trials. Before the 1970’s these measures were known, generically, as performance measures or health status measures. Relabeled as “quality of life measures” they were first used in cancer trials. In the early 2000’s they were relabeled again as “patient-reported outcome measures” or PROMs, in their service to the FDA to support drug labeling claims. To the limited degree (...) that the philosophical literature addresses these measures, it tends to associate them with two major theories of well-being: subjective well-being and the capabilities approach. In this paper, I argue that philosophers ought to treat quality of life measures/proms as a distinct from these theories. I argue that quality of life/proms serve healthcare as vehicles for patient-centered care and this has important consequences for how we theorize these measures. To this end, two requirements set them apart from measures of subjective well-being and the capabilities approach: quality of life/proms need to be patient-directed and inclusive. (shrink)
